Log Message:
lint: turn O(n^2) to O(n) for list of arguments to lint child processes

Previously, adding an argument to the lint child processes (cpp, lint1,
lint2) each time searched the list of arguments for the terminating
null pointer and then reallocated the memory for storing the strings.

Replace the above with a standard resizable array implementation and
give it a proper name, to avoid 'char ***' in the code.

The terminating null pointer in the lists is only required when passing
the list to execvp.  In all other cases it's not needed, so drop it.

No functional change.
